Can I safely put a blanking plate in place of the factory recirc valve and not have any external dump valve?

I know this causes the turbo to stall and produces the 'chatter' sound, which I prefer over a dump valve.

Can I do this on my ME7 T5 without upsetting the ecu?

Whilst I'm aware that causeing the turbo to stall everytime I lift off the throttle might shorten it's life a little, Ive also read people saying T5's don't run high enough boost levels to cause concern?

Any advice will be greatly appreciated
cheers
